Black Adder RS
BULLS
Crosscountry
Black Adder RS is a carbon cross-country mountain bike (2023), by Bulls, part of the Black Adder family. This model is best for a wide range of riders thanks to its fit flexibility, with a balanced riding position, while being best for smoother trails and efficient rolling. Its profile is strongest in areas like all-round climbing capability rather than a narrow specialty, good fit flexibility for dialing in rider position, and balanced, versatile speed for everyday riding. The trade-off to keep in mind is a value score that depends more on priorities than pure price efficiency. Compare this bike with other cross-country bikes on MatchBikes.com.
